Pete, just a observation, you might have already mentioned this (i'll have a read through)

When I uploaded that little animated gif, it shows the thumbnail now. But it's only animated when you first upload it, then when you view the item it's no longer animated. Not a big deal, just wondered if that was how it was supposed to work now?

Created a user, 'regular member', when I first installed LevGal I set the quotas to some insane limits since I'm messing about locally. Uploaded some files in bulk and that went without a hitch from my admin account. Just about every file I tried to upload from the regular member account failed with the message that the file was too large.

No matter which file I chose different pixels and sizes it always failed. I made no changes whatsoever and it eventually started to work. Its hard to determine the cause since it seemingly resolved itself. I'll create another user and see what happens.

To be completely honest, I do not remember exactly what it said. Since it resolved itself it hasn't happened again, even after several hundred uploads where I'm sure some images or files are larger than the one it originally choked on.
